Cadillac's CT6 Flagship Will Have an Aluminum Body And Won't be a Mercedes S-Class Fighter

Set to be unveiled sometime in 2015, Cadillac’s upcoming rear-wheel-drive flagship, the CT6, is fully intended to take on the world of luxury sedans at the highest levels. And because of its expected size, weight will be a factor. To help counter that, a new report from Automobile is claiming the CT6 will feature an aluminum body, thus keeping it in line with the smaller CTS’s 3,700-4,100-pound weight category. What’s more, the CT6 will be slightly smaller than the Mercedes-Benz S-Class.

In other words, the CT6 will aim specifically at luxury four-door coupes like the Mercedes CLS-Class, Audi A7, and BMW 6 Series Gran Coupe. But to be perfectly clear: the CT6 will not be classified as a four-door coupe; it’ll be a true sedan. We also previously learned that Cadillac is diligently working on a sedan even larger than the CT6, possibly to be named the CT9. That will become the official S-Class fighter, but don’t expect it to arrive until around 2017 at the earliest.
